Here are the three different blue soaps I’ve made to date for color comparison: The methods: For the left one, made just over a month ago with jagua from BB - the jagua was dispersed in water and then added directly to the batter as described here. For the middle one, made just under a month ago with indigo from Nuture - the indigo was dispersed in oils and then added to the oils for a dark blue batch of high water batter that I then mixed with low water white batter, as incompletely described here. For the right one, made yesterday with the same indigo added to the lye water, are here. So many ways to get blue! The jagua soap has darkened considerably, including the white section. I don’t have my notes handy, but maybe I had some darker olive oil in that batter. I wasn’t using FOs at that point. (Do any EOs cause discoloration?) The first indigo soap may be getting deeper blue based on the original pics, but it could also be the lighting, which I am not controlling for. Notice how there is some purple bleeding into the glycerin rivers? Cool! That inspired me to mix the indigo powder with 91% alcohol and now the alcohol is turning purple. Maybe there is purple soap in my future! I also want to try mixing in a little Calendula or turmeric oil with indigo to see if I can get a green. I’ve read about others doing it successfully, but apparently it’s quite tricky to get the proportions just right.
